Squalene is an oily compound the human body makes itself, where it helps keep skin supple and acts as an antioxidant. Deep-water sharks are naturally rich in it, along with alkylglycerols (AKGs), and Costar extracts it into a 1000mg capsule.
It has a long history of traditional use in Australia for skin moisture and general wellbeing. The benefits described are traditional uses, not proven medical outcomes.
